Abstract:
We report the long-term follow-up of a patient with rheumatic mitral valve disease who underwent annuloplasty with a specially developed C-ring (the Cooley C-ring) for mitral valve repair in 1977. The repaired valve remained competent and unobstructed for 27 years before requiring replacement.
